Okay do I have money to buy the off-road h pipe but I have emissions here in Utah and I would just switch to my factory pipe when I have emissions, but I am just afraid by switching back and forth I will screw things up and not be able to pass emissions what you guys think?

If you'r 02 year and up you need extensions and you will not need to buy new o2 sensors. O2 sensors are tuff to get out unless you have a o2 socket made for it and also spray a little pb blaster on it to knock off rust. I have the MAC h-pipe on mine and YES very noticeble difference. I like h over x pipes

Yes. Have you ever taken off a stock mid pipe? The passenger side is a b!$& to get off. The top bolt is the hardest and it can easily be rounded off. I used extensions that wobble and it worked like a charm. Pb blaster is your best friend during this job.

Okay so my dad talked me out of getting the pipe and buying something else for the car sense my emmisions are in may ill just buy one after that so it will be summer then and be warm to put it on. So now I got to decide what to get?

The gauge ring bezels and mgw ebrake handle and redoing my interior in carbonfiber. But I am now thinking wheel spacers sense I have the stock 17x8 bullits still to give me a wider stance since I'm lowered it will look good?
